Trump will hold a news conference at his Mar-a-Lago resort in Florida

The Thursday news conference would be his first public appearance since Vice President Kamala Harris became the Democratic presidential nominee and selected Minnesota Gov. Tim Walz as her running mate.

The former president announced the 2 p.m. EDT news conference on his Truth Social network and then posted he was eager to debate Harris. He had teased an announcement on the presidential debate earlier this week after pulling down from the scheduled ABC News debate. Trump had said he would rather the debate be on Fox News, but on Wednesday was showing willingness to reconsider ABC News.

“I will expose Kamala during the Debate the same way I exposed Crooked Joe, Hillary, and everyone else during Debates,” he said on Truth Social. “Only I think Kamala will be easier.”

Secretaries of state urge Elon Musk to fix AI chatbot spreading election misinformation on X

Five secretaries of state are urging Elon Musk to fix an AI chatbot on the social media platform X, saying in a letter sent Monday that it has spread election misinformation.

The top election officials from Michigan, Minnesota, New Mexico, Pennsylvania and Washington told Musk that X’s AI chatbot, Grok, produced false information about state ballot deadlines shortly after President Joe Biden dropped out of the 2024 presidential race.

While Grok is available only to subscribers to the premium versions of X, the misinformation was shared across multiple social media platforms and reached millions of people, according to the letter. The bogus ballot deadline information from the chatbot also referenced Alabama, Indiana, Ohio and Texas, although their secretaries of state did not sign the letter. Grok continued to repeat the false information for 10 days before it was corrected, the secretaries said.
